Bash script to migrate important stuff from your old mac to this one using SSH and rsync

migrate-mac.sh

# MacBook Migration Script
#
# A simple script to move over your important stuff. 
# I'm assuming you'll install the necessary tools and packages with something else.
#
# Prepare your mac before running this:
#  1. Enable SSH access on your old machine
#  2. Go to System Settings > Privacy & Security > Full Disk Access
#     and enable it for "sshd-keygen-wrapper"
#  3. On your new mac, download this script and make it executable by running 
#     `$ chmod +x migrate-mac.sh`
#
# Now run the migration with a `$ ./migrate-mac.sh`
# 
#!/bin/bash

# Set variables
OLD_MAC_IP="YOUROLDMACIP"
NEW_MAC_USER="USERNAME"
BACKUP_DIR="/Users/$NEW_MAC_USER/OldMacBackup"

# Create backup directory on the new MacBook
mkdir -p "$BACKUP_DIR"

# 1. Copy important directories
echo "Copying important directories..."
rsync -avz -e ssh "$NEW_MAC_USER@$OLD_MAC_IP:/Users/$NEW_MAC_USER/{Documents,Desktop,Downloads,Pictures,Music,Movies}" "$BACKUP_DIR/"

# 2. Copy dotfiles and important hidden folders
echo "Copying dotfiles and important hidden folders..."
rsync -avz -e ssh "$NEW_MAC_USER@$OLD_MAC_IP:/Users/$NEW_MAC_USER/{.bash_profile,.bashrc,.zshrc,.gitconfig,.vimrc,.docker,.bash_history,.oh-my-zsh}" "$BACKUP_DIR/"

# 3. Copy SSH keys and config
echo "Copying SSH keys and config..."
rsync -avz -e ssh "$NEW_MAC_USER@$OLD_MAC_IP:/Users/$NEW_MAC_USER/.ssh" "$BACKUP_DIR/"

# 4. Copy development-related directories
echo "Copying development directories..."
rsync -avz -e ssh "$NEW_MAC_USER@$OLD_MAC_IP:/Users/$NEW_MAC_USER/{Projects,Code,Workspace,Development}" "$BACKUP_DIR/"

# 5. Set up SSH keys on the new MacBook
echo "Setting up SSH keys..."
mkdir -p ~/.ssh
cp "$BACKUP_DIR/.ssh/id_rsa"* ~/.ssh/
chmod 600 ~/.ssh/id_rsa
chmod 644 ~/.ssh/id_rsa.pub

# 6. Copy dotfiles and important hidden folders to their proper locations
echo "Setting up dotfiles and important hidden folders..."
for item in .bash_profile .bashrc .zshrc .gitconfig .vimrc .docker .bash_history .oh-my-zsh; do
    if [ -e "$BACKUP_DIR/$item" ]; then
        cp -R "$BACKUP_DIR/$item" ~/"$item"
    fi
done

echo "Migration complete! Please review the transferred files and configurations."
